The Prism-IPX ipBSC Model Version 2 is a network base station controller designed for use with the Prism-IPX PriMega series of text message handling systems.

Encoded paging data from the PriMega encoder software is sent via Unicast to the ipBSC(s) in systems with a few ipBSC’s, or to the Dispatcher module which handles sending individual data packets to many ipBSC’s. Raw paging data issorted into dedicated protocol queues for processing when transmission algorithms are ready for the data.

At each paging transmitter site a GPS unit is used to provide data synchronization and precise transmitter frequency control using the clock reference derived from the GPS 1 pulse per second and related timing packets. Paging data is transmitted simultaneously from each site using the GPS clock pulse as its timing source.
